Boy found fatally wounded in Watford block of flats
A 15-year-old boy has died after being found fatally wounded in a block of flats.
The injured teenager was discovered in Water Lane, Watford, at about 14:30 BST on Monday.
An air ambulance was sent to the flats but the boy was pronounced dead on the fifth floor.
Hertfordshire Constabulary said no arrests been made in connection with the death, which is being treated as "suspicious".
The cause of the boy's death has not been confirmed and a post mortem examination will be carried out, the force added.
A police spokeswoman said she could not comment on the nature of the boy's injuries or whether a murder inquiry had been opened.
"The incident is currently being treated as suspicious and investigations continue to establish the circumstances around what happened," she added.
The East of England Ambulance Service sent two ambulances but despite the efforts of paramedics "the patient went into cardiac arrest" and "was pronounced dead at the scene".
"Our thoughts are with all of those involved at this time," a spokesman added.
